Gaul grew up with his mother and grandparents. Gaul was described as a "top" student who loved to play video games.

In the fall of 2014, Walker was a 14-year-old freshman when she met Gaul, who was a 16-year-old junior student. Gaul, who was dating another girl, told Walker that he was breaking up with his girlfriend to date her, even promising to be her prom date. However, he didn't keep his promise and went to the prom with his then-girlfriend.{{Cite news |last=Sederstrom |first=Jill |date=September 16, 2021 |title=Unlikely Teen 'Heroes' Step In To Help Solve Case Of Murdered 16-Year-Old Girl |url=https://www.oxygen.com/dateline-secrets-uncovered/crime-news/emma-watson-murdered-by-teen-boyfriend-as-she-slept |work=Oxygen}} Although Walker didn't like it, she let it go. Shortly after, Gaul and Walker began dating.

At the beginning of their relationship, people close to the couple described Gaul as very attentive and kind to Walker, and they also said that Walker seemed happy with him. Although their relationship seemed "perfect" at first, Walker's friends and relatives began to notice possessive and toxic behavior from Gaul. Gaul didn't like Walker spending time with anyone other than him or doing things he didn't approve of. For two years, Walker and Gaul had an on-and-off relationship.{{Cite news |last=Diaz |first=Joseph |last2=Valiente |first2=Alexa |date=September 14, 2018 |title=How a college football player's friends helped police expose him for killing his high school cheerleader ex-girlfriend |url=https://abcnews.go.com/US/college-football-players-friends-helped-police-expose-killing/story?id=57776531 |work=ABC News}} Walker's parents considered the relationship toxic.{{Cite news |last=Satterfield |first=Jamie |date=May 1, 2018 |title=Defense: William Riley Gaul wanted to be his girlfriend's hero, not her killer |url=https://www.knoxnews.com/story/news/crime/2018/05/01/defense-william-riley-gaul-wanted-his-girlfriends-hero-not-her-killer/566551002/ |work=Knoxville News Sentinel}} In October 2016, they grounded Walker and banned her from contacting or continuing the relationship with Gaul.

Eventually, Walker attempted to end her relationship with Gaul in November, but Gaul refused. He sometimes threatened to commit suicide if Walker broke up with him. They eventually ended their relationship, but Gaul continued to contact Walker anonymously. Gaul lied to Walker about being kidnapped in an attempt to make her feel sorry for him and date him again. On November 18, 2016, Gaul allegedly sent an anonymous message to Walker instructing her to leave her house and find him "unconscious" on the street.{{Cite news |last=Satterfield |first=Jamie |date=May 2, 2018 |title=Witnesses detail bizarre staged kidnapping two days before Central High cheerleader slain |url=https://www.knoxnews.com/story/news/crime/2018/05/02/william-riley-gaul-trial-witnesses-detail-staged-kidnapping-before-central-high-cheerleader-slain/570824002/ |work=Knoxville News Sentinel}} According to Walker's friends, she was angry and frightened by his deceit. Despite Gaul's continued insistence that he had been kidnapped, Walker did not believe him. Two nights before the incident, a man dressed entirely in black tried to scare Walker.

On November 18, 2016, Gaul stole a 9mm Glock from under the seat of his grandfather's vehicle. When the gun disappeared, Gaul's grandfather feared he had taken it to commit suicide.

On November 21, 2016, Around 12:30 a.m., Gaul headed to Walker's house in Sterchi Hills neighborhood from his dorm in Maryville College, but not before calling a friend to ask how to 'remove fingerprints' from a gun. Gaul fired two shots from different locations outside the home into the area where Walker's bed was located. One of the gunshots struck the side of her head, killing her.{{cite court|litigants=State of Tennessee v.

In the morning, at approximately 6 a.m., Walker's mother went to wake her up. When she arrived, she found that her daughter was not breathing and called 911.

That morning, the Sheriff’s Deputies were dispatched to the Walker home after a 911 call reported a possible suicide. Lead forensic technician of the Knox County Sheriff's Office (KCSO) discovered a bullet hole in the bedroom wall, leading her to suspect it was not a suicide. When Lead Detective Allen Merritt arrived, he noticed another bullet hole in the wall, about shoulder height, and found two shell casings outside. One bullet struck her behind the left ear, and the other lodged in her pillow. The house was quickly secured as a crime scene.

Detective Merritt and other detectives of the Knox County Sheriff’s Office Major Crimes Division began investigating and questioning Walker's family and friends. During interviews, Gaul was frequently mentioned due to his relationship with Walker. A close friend of Gaul, Alex McCarty, informed Merritt that Gaul had stolen a gun from his grandfather the weekend Walker died.{{Cite news |date=April 30, 2018 |title=Testimony: Riley Gaul sent Snapchat telling roommate not to talk to police |url=https://www.wvlt.tv/content/news/Trial-to-begin-for-man-accused-of-killing-Knoxville-cheerleader-481233771.html |work=WVLT}} When detectives questioned Gaul, he denied showing his grandfather's gun to his friend and claimed he did not have the gun in his possession.

Shortly after, Gaul sent a message to his friends asking them not to talk about this to the detectives anymore. The authorities confirmed that the bullets were from a 9mm Glock, the same missing weapon owned by Gaul's grandfather. McCarty and another friend of Gaul's, Noah Walton, who were convinced Gaul was lying, collaborated with authorities to help recover the murder weapon and other physical evidence.

That day, detectives equipped McCarty and Walton with microphones, a transmitter, and a hidden video camera. Walton invited Gaul to his house under the pretense of playing a video game, and recorded him on camera.{{Cite news |title=Alex McCarty & Noah Walton: Football Star’s Friends Helped Police Arrest Him |url=https://heavy.com/news/alex-mccarty-noah-walton-riley-gaul/ |work=Heavy}} During the meeting, Gaul denied killing Walker and suggested that McCarty and Walton tell the detectives they were under the influence of alcohol. Gaul then proposed going to the Bluffs, a wooded area near to a river. They stopped at Gaul's stepfather's house, where Gaul had hidden the gun in the basement, but did not let them see it. Gaul had hidden gloves, trash bags, tennis shoes, black tape, and black clothing inside the same trash bag that contained the gun. The items in the bag were believed to be same black clothing worn by Gaul. Gaul planned to get rid of the gun so that the authorities could not link it to the murder. After seeing the gun, McCarty exclaimed, "Oh my God! That is a real gun," while Walton notified the authorities. A minute later, Gaul was arrested.

Gaul was indicted with first-degree murder, felony murder, tampering with evidence, stalking, reckless endangerment, possessing a firearm during a dangerous felony and theft between $500 and $1,000, in relation with the killing of Emma Walker.

Gaul's family posted his $1 million bail. During the hearing in October 2017, Gaul's defense attorney Wesley Stone asked the Judge Bobby R. McGee for more time to prepare his case. The judge granted that motion and postponed the trial date until April 2018.{{Cite news |title=Jury seated for Riley Gaul murder trial |url=https://www.wbir.com/article/news/crime/jury-seated-for-riley-gaul-murder-trial/51-547197042 |work=WBIR}}

The trial started on April 30, 2018, in the Knox County Criminal Court.

On May 1, Walker's family took the stand to recount the day of the murder. Two of the family's neighbors, the 911 operator who took Jill Walker's call, and one of the investigators on the case also testified.{{Cite news |title=Victim's family members testify in Riley Gaul murder trial |url=https://www.wbir.com/article/news/crime/victims-friends-and-family-members-testify-in-riley-gaul-murder-trial/51-547605366 |work=WBIR}}

On May 2, five friends of Walker testified about the day Gaul lied about being kidnapped. They also mentioned that Walker had sent them a text shortly before her killing, describing a man dressed in black who had been near her home.{{Cite news |title=Gaul trial: Friends say Emma Walker feared she would die in days before shooting |url=https://www.wbir.com/article/news/crime/gaul-trial-friends-say-emma-walker-feared-she-would-die-in-days-before-shooting/51-548124855 |work=WBIR}} In the text, Walker said she was scared, and thought she was going to die. Gaul's grandfather and stepfather also testified at the trial. Gaul's grandfather confirmed that his gun was a 9mm glock.

Audio of Jill Walker's 911 call and videos recorded by Gaul's friends were played at the trial.{{Cite news |last=Luperon |first=Alberto |date=May 4, 2018 |title=William Riley Gaul Murder Trial Day 4 |url=https://lawandcrime.com/high-profile/watch-live-college-football-player-on-trial-accused-of-killing-16-year-old-ex-girlfriend-4/ |work=Law & Crime}}

The defense attorney Stone did not deny that Gaul shot Walker, but argued that Gaul was trying to win her back as part of a series of ploys, which included faking his own kidnapping and attempting to pose as Walker's "rescuer". Prosecutors Kevin Allen and Molly Martin stated that Gaul had planned to kill Walker because she broke up with him. They said that Gaul knew exactly where to shoot to ensure the bullets would hit Walker's head.{{Cite news |last=Satterfield |first=Jamie |date=May 4, 2018 |title=William Riley Gaul fired fatal shots and then slept, testimony showed |url=https://www.knoxnews.com/story/news/crime/2018/05/04/witness-william-riley-gaul-went-bed-after-girlfriend-shot/579590002/ |work=Knoxville News Sentinel}}

On May 8, the jury found Gaul guilty of all charges. The stalking charge was reduced to the lesser-included offense of stalking, and the firearm during a dangerous felony charge was reduced to the lesser-included offense of possessing a firearm during a dangerous felony.{{Cite news |last=Luperon |first=Alberto |date=May 8, 2018 |title=Football Player William Riley Gaul Found Guilty in Murder of Cheerleader Emma Jane Walker |url=https://lawandcrime.com/high-profile/william-riley-gaul-verdict-murder-guilty-emma-jane-walker-cheerleader-football-player/ |work=Law & Crime}}

Judge McGee immediately sentenced Gaul to life in prison without the possibility of parole for 51 years.

In 2021, Gaul requested a new trial based on claims of insufficient evidence, but the motion was denied. Gaul then appealed to the Tennessee Court of Criminal Appeals. In February 2023, the appellate judge ruled to uphold his murder conviction and modified the felony theft conviction.

The Health Occupation Students of America (HOSA) and the cheerleading squad at Central High School established a scholarship in Emma Walker's name called the "Emma Walker Memorial Scholarship".{{Cite web |date=December 8, 2016 |title=Central High School Students Establish Emma Walker Memorial Scholarship |url=https://www.knoxschools.org/site/default.aspx?PageType=3&DomainID=963&ModuleInstanceID=34394&ViewID=6446EE88-D30C-497E-9316-3F8874B3E108&RenderLoc=0&FlexDataID=35235&PageID=3019}}
